display sonar information on a circular depth
scale. The scale indicates what is beneath
your boat. It is organized as a ring that starts
at the top and progresses clockwise. Sonar
information flashes on the ring when it is
received at the depth indicated. The colors
indicate different strengths of the sonar
return. (When using the white default color
scheme, red indicates the strongest return,
blue indicates the weakest return, and white
indicates no return.)
